About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7556140199. Listed at 13 retailers as of November 4, 2026, with prices from $1,164 to $2,607, a $1,443 spread on the same certified stone. MOH London lists it at $2,607. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
